Choosing an Utilities API
Is there a free Utilities API?
Yes. TimeAPI.io, Bored, Color Name API, ColorMagic, Colormind and 23 others are free to use, and QuickChart, Bitly, Abstract Website Screenshot API, ApiFlash, Bly.to and 31 others have a free tier alongside paid plans.
Which Utilities APIs work without an API key?
QuickChart, TimeAPI.io, Bored, CodeCogs Equation Editor, Color Name API and 28 others need no key or sign-up, so you can try them with a plain request.
Can I call an Utilities API from front-end JavaScript?
QuickChart, CodeCogs Equation Editor, Color Name API, Colormind, DigiDates and 19 others allow cross-origin requests and need no key, so they work straight from the browser. For the others, call them from your server so your key stays private.
Can I use Utilities APIs in a commercial project?
QuickChart, Abstract Website Screenshot API, ApiFlash, Bly.to, Brandfetch Logo API and 17 others permit commercial use. CodeCogs Equation Editor, Colormind, Screenshotlayer, TimeZoneDB, UrlBae and 1 other restrict it, for example to non-commercial or attributed use, so read the terms first.
Which Utilities APIs work with AI agents?
FluentEDI, LogoKit, OpenQR, Renderwolf and Shotanvil have both an MCP server and an OpenAPI spec. Bitly, Framejet, Motomarks, Screenshot Scout and ShotOG have an MCP server, so an AI agent can call them directly. QuickChart, TimeAPI.io, Abstract Website Screenshot API, Browshot, Image-Charts and 6 others publish an OpenAPI spec for generating clients and tools.
